WIDE Project

WIDE Project is a research consortium about the Internet technology; so far, this project is composed of more than 100 companies and approximately 70 universities. WIDE project is famous for supporting the Internet from early times and establishing the Internet infrastructure in Japan, and is broadly recognized as a representative research organization of Japan. WIDE project has a lot of collaboration with intranatinal or international companies and research organizations to construct and manage experimentation networks for promoting researches and developments of the next generation Internet. With real experiments of technologies developed by university and company researchers, many of the technologies have been commercialized.

Live E! Project

Live E! Project aims to construct and develop an “Electronic”information infrastructure (broad-area sensor network platform). WIth this platform, one can distribute information of widespread areas in real-time, using environmental sensors connected to the Internet. So far, Live E! Project has deployed 10 distributed servers and approximately 100 sensors. The sensors are now located in 19 countries: Japan, Bangladesh, Cambodia, Canada, China, Chinese Taipei, Egypt, Fiji, France, India, Indonesia, Myanmar, Malaysia, Pakistan, Philippines, Sri Lanka, Thailand, and Vietnam. These environmental data can be applied to various areas such as disaster control, antipollution, education, green IT, agriculture, business planning etc. Its research area contains "overlay network", "distributed database", "distributed stream system", "embedded system", "architecture realization" and so on.

Green UT Project

In Green UT Project, we regard the Building 2 (Engineering Department, The University of Tokyo) as the location of the proof experiment and inspect the meaning and effect of new technologies for environment problems. This project aims at solving earth environment problems by using IT technologies, and achievement of saving energy of IT environment itself. Through research and development, we measure several data, control facility systems, and establish management technics in multi-vendor environment.

TAHI Project

TAHI Project is the joint effort formed with the objective of developing and providing the verification technology for IPv6 in 1998. The project is formed by Yokogawa Electric Corp., KEIO University, and the University of Tokyo. The project researches and develops conformance tests and interoperability tests for IPv6 deployed by KAME Project. Since 2001, the project started to consider the requirements for IPv6 standards for nodes having limited computing resources such as "Home Appliances" and "PDA" and research and develop the reference software and the evaluation and verification system for them.

Next Generation IX Consortium

The target of this consortium is to research and develop systems architectures, especially broad-area distributed IX systems with MPLS, for a realization of more efficient traffic exchange model in distributed environments among contents providers, access providers and back-bone providers, and this consortium is made of nationwide or regional Internet providers, network devices vendors, system integrators, universities and so on. As a technology for traffic exchanges between Internet providers, ones usually establish IXs then manage them. However, commonly proposed IX technologies have had bandwidth limitation and operational problems because of its dependency on data-link media. In addition, scale-limitation makes it difficult to deploy these technologies to wide-area distributed systems, so we all have the problem that the IXs concentrate on the biggest city.

JGN2 plus

Japan Gigabit Network (JGN) is High Speed Advanced Testbed Network for Research and Development (R&D), which is operated by National Institute of Information and Communications Technology (NICT). JGN is promoted with cooperation among government, industry and academia, and also collaborated with communal and international networks.

On 1999, JGN started operation of domestic optical fiber network. From 2004, As JGN2, They added domestic and international access point, increased network bandwidth, started IPv6 routing and installed optical switches. Moreover, From 2008, As JGN2plus, They,''Service Platform Architecture Research Center''(SPARC) are operating testbed network which is providing various services for research and development of next generation network.
